SIGNAL COMMUNICATION SYSTEM AND METHOD FOR A VEHICLE SYSTEM
First Claim
1. A communication system comprising:
- a first wireless communication device configured to be disposed onboard a vehicle system having two or more propulsion-generating vehicles that are mechanically interconnected with each other in order to travel along a route together; and
a controller configured to be disposed onboard the vehicle system and operatively connected with the first wireless communication device in order to control operations of the first wireless communication device, the controller configured to direct the first wireless communication device to switch between operating in an off-board communication mode and operating in an onboard communication mode,wherein, when the first wireless communication device is operating in the off-board communication mode, the first wireless communication device is configured to receive remote data signals from a location that is disposed off-board of the vehicle system and, when the first wireless communication device is operating in the onboard communication mode, the first wireless communication device is configured to communicate local data signals between the propulsion-generating vehicles of the vehicle system.

Abstract
A communication system includes a first wireless communication device disposed onboard a vehicle system having two or more propulsion-generating vehicles that are mechanically interconnected with each other. The communication system also includes a controller configured to be disposed onboard the vehicle system and operatively connected with the first wireless communication device in order to control operations of the device. The controller is configured to direct the first wireless communication device to switch between operating in an off-board communication mode and an onboard communication mode. When the first wireless communication device is operating in the off-board communication mode, the device is configured to receive remote data signals from a location that is disposed off-board of the vehicle system. When the first wireless communication device is operating in the onboard communication mode, the device is configured to communicate local data signals between the propulsion-generating vehicles of the vehicle system.
